Broccoli & Cauliflower Casserole
This cheesy, creamy broccoli and cauliflower casserole carries the perfect amount of sauce to enhance the flavors of the veggies without covering them up. A crunchy, buttery topping adds texture to this easy casserole that will be loved by children and adults alike.
Caprese Zucchini Casserole
A summertime favorite--zucchini casserole--gets an Italian spin in this delicious and healthy side dish with tomatoes, mozzarella and basil. You can use zucchini or summer squash in this caprese-style casserole, or a combination of the two. A sprinkling of fresh basil and a drizzle of balsamic vinegar just before serving brightens up the flavors. Serve with grilled or roasted chicken and some quinoa, rice or couscous to soak up the juices from the casserole for a satisfying and easy dinner.
Tomato & Green Bean Casserole with Spicy Herb Pesto
No gloppy canned soup in this healthy green bean casserole recipe. Simply give cilantro, parsley or chives (or a mix of all three) a whirl in the food processor to make the pesto-like sauce that ties the casserole together.
In this baked asparagus side dish recipe, we smother tender-crisp asparagus spears with a creamy cheese sauce and top the casserole with crispy panko breadcrumbs. Blanching the asparagus first in boiling water helps preserve its vibrant green color. Medium-thick asparagus spears work best for this recipe. If your asparagus spears are very thick, they may need a longer time in the oven.
Spiralized Zucchini & Summer Squash Casserole
If you don't have a spiralizer to make this healthy zucchini noodle casserole (aka zoodles), use a vegetable peeler to make long thin strips of the squash and zucchini, stopping when you reach the seedy center. Just a few minutes under the broiler gives these ricotta-and-basil-filled nests a light golden top.
Spinach, Feta & Rice Casserole
This one-pan recipe is the casserole version of spanakopita! It's hearty enough to enjoy as a vegetarian lunch or dinner, yet versatile enough to serve alongside just about any protein. To make it extra creamy, top each serving with a dollop of sour cream.
Cheesy Eggplant Casserole
This cheesy eggplant casserole has a light custard with deliciously tender and flavorful summer vegetables and fresh herbs. The cheese makes this easy dish creamy and decadent. Enjoy it for brunch or dinner with a green salad on the side.
Chicken & Zucchini Casserole
This baked chicken and zucchini casserole is creamy, hearty and low-carb! The whole family will love this easy casserole, plus it's a great way to get the kids to eat their veggies (concealed in a delicious cheese sauce!).
Cheesy Summer Squash Casserole
This squash casserole is a great rendition of the classic--it's still super cheesy, but much healthier for you. Look for medium or even small squash, as large ones tend to water out more. Be sure to remove as much water as possible after boiling the veggies and before assembling the casserole so it doesn't get soupy.
Vegetarian Enchilada Casserole
Think of this vegetarian enchilada casserole as a veggie-packed Mexican lasagna with corn tortillas standing in for the noodles! If your peppers are mild and you like heat, opt for spicy pico de gallo. This easy vegetarian dinner recipe is sure to become a new family favorite.
Eggplant Tortilla Casserole
This layered casserole is inspired by classic cheese enchiladas, minus the fuss of rolling and stuffing individual tortillas. You'd never guess that within this comforting Tex-Mex casserole hides a layer of thinly sliced eggplant. The thin slices become tender when roasted and add a subtle savory note.
Zucchini Pizza Casserole
Got a bumper crop of zucchini? Try this crowd-pleasing casserole-meets-pizza dish, which can easily be made gluten-free. A layer of tender shredded zucchini is topped with all the classics: sauce, cheese, pepperoni and sliced bell pepper. Experiment with your own favorite toppings, but make sure you don't overload the crust or it will be too wet.
Summer Vegetable Chicken Tortilla Casserole
Summer's harvest--eggplant, corn and zucchini--stars in this healthy, Mexican-inspired casserole that's perfect for serving a crowd or for a dinner with leftovers for the next day.
Summer Vegetable Tian
This pretty vegan layered casserole is so simple to make. Its only seasonings are salt and garlic-infused olive oil, which you make by sizzling a clove of garlic in olive oil for about a minute. This dish is lovely warm or room temperature. Serve with crusty bread as a vegetarian entree or alongside roasted meats as a side dish--don't forget a glass of chilled rosé.
Gluten-Free Eggplant Parmesan
This cheesy baked eggplant Parmesan has no breading, which means it's easier to make than the traditional version. There's no dredging or frying--instead, the eggplant is roasted until tender before being layered in the casserole dish with a tangy homemade tomato sauce, mozzarella and Parmesan cheese. And without breading, this satisfying eggplant Parmesan is also gluten-free!
25-Minute Chicken & Veggie Enchiladas
These chicken enchiladas are great for using up any veggies you have lingering in your fridge. Our chicken enchilada recipe calls for zucchini, squash and onion, but you could easily swap in spinach, onions or potatoes.
Squash-Tomato Bake with Basil and Pine Nut Gremolata
Pine Nut Gremolata is the perfect topping to garnish this baked vegetable dish. This vibrant Italian condiment traditionally accompanies braised veal shank, but cuts through the flavor of this vegetarian side dish brilliantly.
Slow-Cooker Vegetarian Tex-Mex Casserole
You won't believe this enchilada-like casserole isn't made with meat! The smoky chili powder and cumin give it a satisfying meat-like flavor. Look for meatless crumbles in the produce section of the supermarket near the other vegetarian and vegan products. For a twist, swap the meatless crumbles for black beans or ground beef.
Spinach & Mushroom Tortellini Bake
This cheesy tortellini bake is a dish the whole family will love--it's filled with sweet-tasting marinara, mushrooms and spinach and topped with melted cheese. Complete the meal, plus get in another vegetable serving, by adding a side of broccoli or a small green salad.
